Ivalve elawulayo esebenza ngokwakho sisivalo esisetyenziselwa ukulawula uxinzelelo lolwelo, izinga lokuqukuqela, kunye nobushushu. Iyakwazi ukulungelelanisa ngokuzenzekelayo i-outlet yoxinzelelo olusekelwe kwiinguqu kwi-inlet yoxinzelelo ukuze kugcinwe ixabiso loxinzelelo oluqhubekayo. Olu hlobo lwevalve lusetyenziswa kakhulu kwiindawo zoshishino, ezifana neekhemikhali, i-petroleum, amandla, njl.
Uxinzelelo oluzenzekelayo oluqhubekayo, uxinzelelo lwasemva oluzinzileyo, izinga lokuhamba, kunye nevalve yokunciphisa uxinzelelo lomphunga kwimibhobho yenitrogen luhlobo olukhethekileyo lwevalvu elawulayo esebenza ngokuzimeleyo esetyenziswa kwiinkqubo zemibhobho yenitrogen. Iyakwazi ukulungelelanisa ngokuzenzekelayo uxinzelelo kunye nesantya sokuhamba kwe-nitrogen ukugcina ixabiso elizinzileyo loxinzelelo lwangasemva. Olu hlobo lwevalve luhlala luqulathe amacandelo afana nomzimba wevalvu, isigqubuthelo sevalvu, isihlalo sevalve, idiski yevalve, intwasahlobo, njl.
Itheyibhile yokuthelekisa ubungakanani bemodeli:
|Imodeli | Idayamitha yegama (DN) | indlela yoqhagamshelwano | uxinzelelo lokusebenza (MPa) | indawo esebenzayo|
|— |. ——– |
|ZL-1 | 15-50 | uqhagamshelwano lweflange | 0.6-1.6 | igesi yenitrogen |
|ZL-2 | 50-80 | uqhagamshelwano lweflange | 1.0-2.5 | igesi yenitrogen |
|ZL-3 | 80-150 | uqhagamshelwano lweflange | 1.6-4.0 | igesi yenitrogen |
|ZL-4 | 150-200 | uqhagamshelwano lweflange | 2.5-6.4 | igesi yenitrogen |
|ZL-5 | 200-300 | uqhagamshelwano lweflange | 4.0-10.0 | igesi yenitrogen |
Le milinganiso ingentla yeyokuba ireferensi kuphela, kwaye ukhetho oluthile kufuneka lugqitywe ngokusekelwe kwiimeko zokusebenza kunye neemfuno.
